AMERICAN HELLHOLE: HUMANS AS SOCIAL CREATURES

In an unusual statement, Atul Gawande, the Harvard surgeon, argues in the March 30 edition of the New Yorker that solitary confinement is equivalent to torture. In his inimitable fashion, Gawande marshalls research, national demographics and contrasts to much of the civilized world to support his thesis.

Reading it for the second time, I realized that I could give readers a sense of its relevance through the initial paragraphs, so. . .

Human beings are social creatures. We are social not just in the trivial sense that we like company, and not just in the obvious sense that we each depend on others. We are social in a more elemental way: simply to exist as a normal human being requires interaction with other people.

Children provide the clearest demonstration of this fact, although it was slow to be accepted. Well into the nineteen-fifties, psychologists were encouraging parents to give children less attention and affection, in order to encourage independence. Then Harry Harlow, a professor of psychology at the University of Wisconsin at Madison, produced a series of influential studies involving baby rhesus monkeys.

He happened upon the findings in the mid-fifties, when he decided to save money for his primate-research laboratory by breeding his own lab monkeys instead of importing them from India. Because he didn’t know how to raise infant monkeys, he cared for them the way hospitals of the era cared for human infants—in nurseries, with plenty of food, warm blankets, some toys, and in isolation from other infants to prevent the spread of infection. The monkeys grew up sturdy, disease-free, and larger than those from the wild. Yet they were also profoundly disturbed, given to staring blankly and rocking in place for long periods, circling their cages repetitively, and mutilating themselves.

At first, Harlow and his graduate students couldn’t figure out what the problem was. They considered factors such as diet, patterns of light exposure, even the antibiotics they used. Then, as Deborah Blum recounts in a fascinating biography of Harlow, “Love at Goon Park,” one of his researchers noticed how tightly the monkeys clung to their soft blankets. Harlow wondered whether what the monkeys were missing in their Isolettes was a mother. So, in an odd experiment, he gave them an artificial one.

In the studies, one artificial mother was a doll made of terry cloth; the other was made of wire. He placed a warming device inside the dolls to make them seem more comforting. The babies, Harlow discovered, largely ignored the wire mother. But they became deeply attached to the cloth mother. They caressed it. They slept curled up on it. They ran to it when frightened. They refused replacements: they wanted only “their” mother. If sharp spikes were made to randomly thrust out of the mother’s body when the rhesus babies held it, they waited patiently for the spikes to recede and returned to clutching it. No matter how tightly they clung to the surrogate mothers, however, the monkeys remained psychologically abnormal.

In a later study on the effect of total isolation from birth, the researchers found that the test monkeys, upon being released into a group of ordinary monkeys, “usually go into a state of emotional shock, characterized by . . . autistic self-clutching and rocking.” Harlow noted, “One of six monkeys isolated for three months refused to eat after release and died five days later.” After several weeks in the company of other monkeys, most of them adjusted—but not those who had been isolated for longer periods. “Twelve months of isolation almost obliterated the animals socially,” Harlow wrote. They became permanently withdrawn, and they lived as outcasts—regularly set upon, as if inviting abuse.

The research made Harlow famous (and infamous, too—revulsion at his work helped spur the animal-rights movement). Other psychologists produced evidence of similarly deep and sustained damage in neglected and orphaned children. Hospitals were made to open up their nurseries to parents. And it became widely accepted that children require nurturing human beings not just for food and protection but also for the normal functioning of their brains.
